Electromagnetic self-force of a point charge from the rate of change of the momentum of its retarded self-field
arXiv:1902.04488
Abstract
The self-force of a point charge moving on a rectilinear trajectory is obtained, with no need of any explicit removal of infinities, as the negative of the time rate of change of the momentum of its retarded self-field.
